Why do my new batteries seem weak?
Deep-cycle batteries employ a much different chemical technology than
that used in car batteries, nickel-cadmium (nicads), or in other common
battery types. Deep-cycle batteries are specifi cally designed to provide
power, drain down their charge, and then accept a relatively quick recharge.
AGM and Gel-Cell batteries should be charged as often as possible. They
do not have a “memory” like nickel-cadmium batteries.
We work closely with our battery manufacturer to provide a battery that
best suits your power chair’s specifi c demands. Fresh batteries arrive
regularly at Quantum and are promptly shipped with a full charge. During
shipping, the batteries encounter temperature extremes that may infl uence
initial performance. Heat robs the charge from the battery, and cold slows
the power available and extends the time needed to recharge the battery
(just as with a car battery).
It might take a few days for the temperature of the battery to stabilize and
adjust to its new ambient temperature. More importantly, it will take a few
“charging cycles” (a partial drain
—
then a full recharge) to establish the critical
chemical balance that is essential to the battery’s peak performance and long
life. It will be well worth it to take the time to break in your battery properly.
How can I ensure maximum battery life?
A fully charged deep-cycle battery will provide reliable performance and
extended battery life. Keep your power chair’s batteries fully charged
whenever possible. Batteries that are regularly and deeply discharged,
infrequently charged, or stored without a full charge may be permanently
damaged, causing unreliable power chair operation and limited battery life.
NOTE: The useful life of a battery is quite often a refl ection of the care
it receives.
How should I store my power chair and its batteries?
If you do not use your power chair regularly, we recommend maintaining
battery vitality by charging the batteries at least once per week.
If you do not plan on using your power chair for an extended period, fully
charge the batteries prior to storage. Disconnect the battery harnesses
and store the power chair in a warm, dry environment. Avoid temperature
extremes, such as freezing and excessively hot conditions, and never
attempt to charge a frozen battery. A cold or frozen battery should be
warmed for several days prior to recharging.
